Also, 'Steel Container' isn't a Fountation-standard containment device, so it doesn't need to be capitalized.

SCP-XXXX is an Old Radio.Constructed from Wood and other Metal's.

A bunch of the capitalization here— wood, 'old radio', metal— isn't necessary. Also, the plural of 'metal' doesn't need an apostrophe before the S (metal —> metals, not metal's).

Only if 05's order

It isn't 05 (zero-five), it's O5 (the letter O - five).

I'm pretty much out of time for now, but what I can tell you is that the article itself needs a good few proofreading sweeps. No offense, but reading this and looking at the grammar conventions makes me think English isn't your first language.

Idea-wise, it needs something more. The way it is now, it's nothing more than your garden-variety suicide inducer.

The first thing I notice is that the object class should be Safe, and not Euclid. Simply lock this SCP up in a room and it will do absolutely nothing.

In the closing statement of the interview:2 days later he was found dead in his chair by Commiting Suicide.

First; "Commiting Suicide" should not be capitalized. Second; It should be "2 days later he was found dead in his chair by suicide." and not "2 days later he was found dead in his chair by Commiting Suicide."

One thing I saw in the whole document is that you need to have a space after punctuation.
Wrong: "SCP-XXXX is highly Dangerous and should not be spoken to.Only if 05's Order."
Correct: SCP-XXXX is highly Dangerous and should not be spoken to. Only if 05's Order."
By the way, remove the dot before "Only" and use a comma instead. Also remove the apostrophe after "O5".

In description:Constructed from Wood and other Metal's.
"Wood" should not be capitalized and the word "other" can be removed as it suggests wood is a metal. The apostrophe in "Metal's" should be removed as it means: a metal's [Insert noun here]. The apostrophe essentially makes it an owning form instead of a plural.

In description:"When Someone ask's or simply has a conversation with SCP-XXXX, the object tells the person what they want but sometimes manipulate them, and for that reason it is highly guarded."

Swap "the object" with "it" as the object can seem as a different object.

"Addendum: SCP-XXXX is highly Dangerous and should not be spoken to.Only if 05's Order."

This does not require an Addendum and can be stated in the description. See my previous correctly spelled version of this addendum higher up.

As a last note, if you want to I could fix the spelling errors if you give me permission through a reply on this post. This might not be clearest critique but as I guess is the case with you, English is not my first language.
